Leaf problem

Hey guys, anyone know what is causing my leaf problems? I first noticed it a couple weeks ago. My plants are outside in pots the soil is a mixture of pete moss, perlite, and cow manure. I’ve mostly been feeding them bat guano and worm castings, just switched to a high phosphate guano like 2 weeks ago when they started flowering but the leaf problem started before that. It’s on a lot of leaves, I’ve been trying to pick the bad ones off each day without picking too many. I haven’t seen it on any of the newest leaves. Thanks

I wish I could help you - I've never seen that before - looks like a combo of mag / phosphorus deficiency, but as far as the root cause, I'd have no clue. Maybe a PH issue - your pot looks pretty wet, perhaps an over watering issue..

Seriously - Good Luck!

Thanks for the input. I’ve been thinking I’ve maybe been overwatering so I’ll def start with that.
